For a few weeks now, Heatmap’s staff writer, Emily Pontecorvo, has been trying to figure out if installing rooftop solar panels on your home actually reduces carbon pollution in a systematic way. In other words: If you own a home, and install solar panels on it, are you doing anything to change how much fossil fuel gets burned in your region or around the world? Or — somewhat counterintuitively — will your panels just increase the cost of electricity near you while shifting demand for those fossil fuels around?
On this week’s episode, we try to answer these questions in a satisfying way. Princeton Professor Jesse Jenkins and I welcome Emily to the podcast to discuss the messy truth of distributed solar power.

Here is an excerpt from our conversation:
Emily Pontecorvo: My question is, if you're taking this solar-shaped hole out of electricity demand and that's displacing a cheaper utility-scale solar project, how do we go from that to you're not having an effect on emissions? Why is displacing that cheaper option than meaning that it's not as an effective climate action?
Jesse Jenkins: Well, because basically there's a certain amount of demand for solar-shaped production in the electricity system, right? And if you're reducing demand for electricity at exactly the time that a utility solar project would produce, then you're making the economics of building more solar incrementally worse as you add more distributed solar.
We still get basically the same amount of overall solar power in equilibrium. Like, you know, that's the amount that's profitable for people to invest in. It's just that you've shifted it from, again, cheaper projects at larger scale to more expensive projects at smaller scale, particularly in the U.S. We can come back to why the U.S. market is so, I think, broken and so much more expensive than it needs to be.
But particularly in the US, it is much more expensive, like three or four times more expensive, to build a megawatt worth of solar panels in 10 kilowatt increments at a bunch of different homes than it is to build one megawatt of solar on a big landfill or in a farm or on a big box store.
Pontecorvo : So is the idea that, do you get less solar overall or is it?
Jenkins : No, you basically get the same amount. You just get the same amount of solar and it's just more expensive.
Pontecorvo : Why does it matter then? I mean, obviously it matters. It's a better outcome to have a cheaper clean electricity system. But ...
Jenkins: No, it's a great question.
So why does it matter? I mean, there's two questions.
You were asking before, like, does it amount to an effective climate action? Well, if it doesn't increase the overall supply of solar power in the regional grid, then no, it's not an effective climate action.
It might be fine for you to do it as a personal decision for other reasons like economics or feeling like you don't want to keep paying your utility because you don't like the utility and you want to generate your own power. Like there's lots of other reasons why you might do this. Or because you want to save land, right? We can talk about the sort of land-saving potential distributed generation, which I think is probably the best case for it.
But in terms of climate impact, it's null. If you're not increasing the supply of clean energy overall, you're just substituting one clean megawatt hour for another clean megawatt hour.
Why does it matter that we're making that megawatt hour more expensive? Well, at the end of the day, we have to keep our electricity supply affordable as we decarbonize. Both because it's important for equity reasons, because we don't want people who have a hard time paying their bills to have to pay a lot more. But from a climate perspective, because we have to radically expand the amount of electricity supply and decarbonize transportation and heating and industry and make hydrogen and do all these other things, that are going to require electricity to be relatively competitive against the fossil fuels that they're trying to displace in those sectors.

And that’s on top of the constitutional questions.
One of the biggest stories of the new Trump administration is the president’s attempt to block congressionally mandated spending. So far, most of the discussion over this freeze has focused on whether it violates federal law and the Constitution. But another front is likely to open soon in that legal battle — and it has received much less attention.
On his first day in office, Trump froze all federal spending tied to the Inflation Reduction Act and the $1 trillion infrastructure law passed during Joe Biden’s presidency. Although Trump has since relented on other spending freezes — such as a short-lived block on virtually all federal payments — he has continued to withhold these energy, climate, and infrastructure funds, even after a federal judge ordered their release on Monday.
Continuing this freeze for longer than 45 days would take an act of Congress, and it’s unclear whether the Trump administration intends to get one. It seems to be gearing up to fight a Supreme Court battle over whether the president has an inherent “impoundment” authority to block federal funding unilaterally (more on that later).
That constitutional fight will obviously be extremely important. But as hundreds of CEOs and local government officials are now surely realizing, this battle is not the only legal front on which the Trump administration’s spending freeze will be fought.
That is because — as long as the freeze continues — the Trump administration is going to start violating hundreds or even thousands of contracts and legally binding spending agreements. The Trump spending fight is not only about policy and the Constitution, in other words, but also about contract law.
The companies and local governments that are now being strung along by the Trump administration did not make a vague handshake agreement with the Biden administration. Instead, they signed a contract with the federal government to receive a certain amount of money in exchange for doing a certain activity. The administration might have changed since then. But the government is still bound by its debts and obligations.
Those companies have now spent money — in some cases more than tens of millions of dollars — to fulfill their side of the contract. They have bought equipment, purchased land, and hired workers. Those companies’ contracts with the federal government are as legally binding as any other contract between two parties — and the courts are as empowered to defend those contracts as they are any others.
There is a significant amount of money tied up in these agreements. By the end of 2024, the Biden administration had “obligated” more than $96 billion of grants from the Inflation Reduction Act, while the Department of Energy’s loans office had “finalized” more than $60 billion in lending. Both terms generally mean that a contract has been signed.
As Heatmap has written before, just because the government has signed a contract for a certain amount of money doesn’t mean that the money has gone out the door. Many federal contracts are designed, basically, as ongoing invoicing relationships: A private party agrees to do something for the government, the private party does it, and then the private party brings back its receipts and asks the government for reimbursements.
The government has been refusing to make those private parties whole, even though those private parties have kept up their side of their agreements. (Note that at no point, ever, has the Trump administration claimed on the record that the private entities it’s now refusing to pay are in breach of contract. It is simply saying that it would rather not pay them just yet for political reasons.)
This has several important consequences for what is about to happen next.
The first is that the Trump administration is about to face dozens and perhaps hundreds of lawsuits over breach of contract. The president cannot simply announce that the contracts are void, like Michael Scott declaring bankruptcy in The Office. If the president or his officials want to cut off funding to IRA and infrastructure law grant and loan recipients, then they will need to give specific reasons under the contract for terminating and then defend those claims in court — provided that the recipient sues. Under a law called the Tucker Act, companies can sue the federal government for breaching a contract in the Court of Federal Claims, a special court in Washington, D.C. These lawsuits will not be about MAGA policies, but rather about the facts of each contract and whether the parties are in compliance with them.
At the same time, the Trump administration will likely be waging a fight over “impoundment.” Some officials in the Trump administration — including Russ Vought, the Project 2025 architect who now leads the White House budget office — profess that the president has an inherent authority that allows him to unilaterally block federal funding. This is despite the fact that the Constitution does not mention such a capacious authority, and the Supreme Court has historically rejected other presidential ploys, such as President Bill Clinton’s use of the line-item veto, to accept some parts of the federal budget and ignore others.
This will create, at least at first, a two-track legal fight over the Trump administration’s spending freeze. At the high level, President Trump will be fighting over the political and constitutional question of whether he can unilaterally block funding that has been appropriated by Congress. But at the lower level, federal agencies may be sparring with hundreds of companies about whether they can wriggle their way out of the contracts they have already signed. These dozens of potential smaller fights will command an enormous amount of time and personnel attention — not only from the companies, nonprofits, and local governments trying to secure what they are owed, but also from the Trump administration, which has finite resources.
These skirmishes will have economic consequences — and while these might be small in the context of America’s $29 trillion economy, they will gradually deepen. By refusing to honor its contracts, the Trump administration is forcing private companies to bear public costs. Those companies will delay hiring employees and investing in new equipment as they await repayment; some will furlough workers and go bankrupt. The burden will become more and more significant every day that the Trump administration continues its spending freeze.
These costs will not be randomly distributed through the economy, but rather concentrated primarily in sectors located in rural areas and affecting working-class Americans. Professional environmentalists in Seattle will continue to have a job regardless of what happens to some rural school district’s microgrid project. But the construction workers and electricians set to build that grid will lose income.
For this reason, the energy and infrastructure freeze does not strike me as a very wise move, politically — particularly as U.S. economic sentiment is worsening. One reason it is politically prudent for lawmakers, and not the president, to make spending decisions is that representatives understand their districts much better than federal officials in Washington, D.C.
This suggests the final takeaway: The Trump administration is beginning to play a very dangerous game with the United States. The American economy’s strength and prosperity arises from its territorial resource wealth, its educated and productive workforce, its secure defensive position, and — crucially — a set of financial intangibles that are ultimately backed up by federal contracts. The federal government is the largest counterparty in the global economy because it can be relied upon to pay its debts. If it begins to back out of contracts hither and thither, especially if primarily for partisan political reasons, then it will ultimately damage every American.
This is not a new or novel thought. Writing in 1790, Treasury Secretary Alexander Hamilton said that the “punctual performance of contracts” was the key to maintaining the United States’ good credit. “States, like individuals, who observe their engagements, are respected and trusted: while the reverse is the fate of those who pursue an opposite conduct,” he said. “Every breach of the public engagements, whether from choice or necessity, is in different degrees hurtful to public credit.”
It isn’t unusual for new administrations to pause some spending at the beginning of their terms, and perhaps the Trump administration will soon prove the worriers wrong and lift the spending freeze. But I fear it will not. It is very possible that in the next several months, the administration will begin to breach dozens of its public engagements. This will hurt the energy, automaking, and construction sectors in the near term. It will cause grief for the president — and, I worry, all of us — soon after.
Core inflation is up, meaning that interest rates are unlikely to go down anytime soon.
The Fed on Wednesday issued a report showing substantial increases in the price of eggs, used cars, and auto insurance — data that could spell bad news for the renewables economy.
Though some of those factors had already been widely reported on, the overall rise in prices exceeded analysts’ expectations. With overall inflation still elevated — reaching an annual rate of 3%, while “core” inflation, stripping out food and energy, rose to 3.3%, after an unexpectedly sharp 0.4% jump in January alone — any prospect of substantial interest rate cuts from the Federal Reserve has dwindled even further.
Renewable energy development is especially sensitive to higher interest rates. That’s because renewables projects, like wind turbines and solar panels, have to incur the overwhelming majority of their lifetime costs before they start operating and generating revenue. Developers then often fund much of the project through borrowed money that’s secured against an agreement to buy the resulting power. When the cost of borrowing money goes up, projects become less viable, with lower prospective returns sometimes causing investors not to go forward .
High interest rates have plagued the renewables economy for years. “As interest rates rise, all of a sudden, solar assets that are effectively bonds become less valuable,” Quinn Pasloske, a managing director at Greenbacker, a renewable investor and operating company, told me on Tuesday, describing how the stream of payments from a solar project becomes less valuable as rates rise because investors can get more from risk-free government bonds.
The new inflation data is “consistent with our call of an extended Fed pause, with only one rate cut in 2025, happening in June,” Morgan Stanley economists wrote in a note to clients. Bond traders are also projecting just a single cut for the rest of the year — but not until December.
Federal Reserve Chair Jerome Powell told the Senate Banking committee Tuesday, “We think our policy rate is in a good place, and we don’t see any reason to be in a hurry to reduce it further.”
The yield for the 10-year Treasury bond, often used as a benchmark for the cost of credit, is up 0.09% today, to 4.63%. While this is below where yields peaked in mid-January, it’s a level still well above where yields have been for almost all of the last year. When Treasury yields rise, the cost of credit throughout the economy goes up.
Clean energy stocks were down this morning — but so is the overall market. Because while high interest rates are especially bad for renewables, they’re not exactly great for anyone else.
Current conditions: Los Angeles is bracing for a massive rain storm that could trigger landslides in areas recently charred by severe wildfires • About 90% of districts in India have received little or no rainfall since the start of the year • Schools are closed in Kansas City, Missouri, where up to 6 inches of snow is expected today.
California’s state-backed insurance plan of last resort is short on funds to pay out claims from the Los Angeles wildfires. As a result, California Insurance Commissioner Ricardo Lara is asking private insurers that operate in the state to give the program, known as the FAIR Plan, $1 billion. The FAIR Plan is for people who can’t get private insurance coverage because their properties are considered high risk. As weather disasters get worse and private insurers pull back from the state, more people are relying on the FAIR Plan, and its policy load has doubled since 2020 to more than 452,000. The plan has received some 4,700 claims related to last month’s devastating fires, and paid out more than $914 million. But that’s not enough. The program expects a loss of $4 billion from the fires. This is the first time in 30 years that the program has needed to ask for more money. The fee will be divided between the private companies according to market share, and they’ll have 30 days to pay. Up to half of the cost can be passed on to their own policyholders. Even so, there are concerns that this will push private insurers to leave California to avoid further losses, exacerbating the state’s insurance crisis. State Farm, the state’s largest insurer, recently asked regulators to approve a 22% rate increase.
The U.S. added nearly 50% more clean energy capacity last year than in 2023, according to a new report from energy data company Cleanview. Most of the 48.2 gigawatts of new capacity came in the form of batteries and solar, with solar additions rising by 65%, mostly in southern states like Texas and Florida. As for battery storage, four states (California, Texas, Arizona, and Nevada) accounted for 70% of new capacity. Meanwhile, wind power missed out on growth, with capacity additions dropping by nearly a quarter year-over-year. The report says solar growth will likely slow down in 2025, battery storage could grow by nearly 70%, and wind capacity could grow by 80% if all planned projects manage to reach completion. One interesting tidbit is that Indiana is emerging as a solar hot spot. It ranks third on the list of states with the most solar additions planned for 2025, below Texas and California, but above Arizona. Of course, a lot will depend on the Trump administration.

Global air traffic rose by 10% to an all-time high last year, according to recent data from the International Air Transport Association. This means more aviation pollution. Air travel already accounts for 2.5% of global energy-related carbon dioxide emissions, and has contributed an estimated 4% to global warming. As Ben Elgin at Bloombergnoted, the rise in air travel comes as airlines fail to adopt “sustainable” aviation fuel at meaningful levels, with SAF accounting for a paltry 0.3% of commercial jet fuel production in 2024. “SAF volumes are increasing, but disappointingly slowly,” the IATA said in December. “Governments are sending mixed signals to oil companies which continue to receive subsidies for their exploration and production of fossil oil and gas.” Airlines are relying on SAF to curb their emissions, with many pledging to consume 10% SAF by 2030. But “even if airlines can somehow replace 10% of their fuel with lower-emitting alternatives by the end of the decade, those climate benefits would be wiped out by the industry’s expected growth,” wrote Elgin. Yesterday the Trump administration released a $782 million loan for a plant in Montana to turn waste fats into biofuel. The loan was originally finalized under the Biden administration.
The CEO of Ford Motor yesterday warned that the company could be forced to lay off workers if President Trump raises tariffs on Mexico and Canada, and guts Biden-era legislation that supported electric vehicle production. “A 25% tariff across the Mexico and Canadian border will blow a hole in the U.S. industry that we have never seen,” Jim Farley said at a conference. He added that ending loans and subsidies for EV manufacturing projects would also put many Ford jobs at risk. The New York Times noted that his comments “offered a rare example of a corporate executive calling into question Mr. Trump’s policies or statements.”
Sales of electric vehicles were up 18% in January compared to the same time in 2024, but growth is slowing, according to research firm Rho Motion. Last month, 1.3 million EVs were sold worldwide. That’s down 35% from December’s numbers, and marks the third month in a row of slowing growth. China’s sales were down last month because of the Chinese New Year. Meanwhile, sales were up in Europe as new emissions standards came into effect. And in the U.S. and Canada, sales rose 22%. Rho Motion expects more than 20 million EVs will be sold this year.
$160 million – The amount raised in a Series B funding round by Chestnut Carbon. The startup focuses on planting trees and vegetation, and improving forest management practices to better remove carbon from the atmosphere. Chestnut will use this latest funding to build out afforestation projects — that is, planting trees in areas where, at least in modern times, forests have not existed.
Editor’s note: This story has been updated to clarify the nature of the Trump administration’s actions on funding for a Montana biofuels plant.
